IMPROVEMENT EN TENONlNG-MACHINES.

Specification forming part of Letters Patent 130,459, dated August 13, 1872.

I, DANIEL Wma-Lock, of the city of Newark, in the county of Essex, inthe State of New Jersey, have invented certain Improvements in Machines for Making the Joints in Window-Sash, of which the following is a specfication.

The object of this invention is to produce in the one machine the means for making the dovetail mortises and tenons, or common mortises and tenons, or only dovetail joints or simple tenons, as maybe desired; and it consists of the combination and arrangement of the several parts of the machine, as is more fully hereinafter described.

In the drawing, Figure 1 is an upright side view of the machine. Fig. 2 is an end view of the saine. Fig. 3 is a plan view of the machine; Fig. 4, plan detail of train of gearing 5 and Fig. 5, a horizontal view of Fig. 3.

A is the upper revolving cutter-head for cutting the shoulders and one side of a tenon, and hung in adjustable horizontal frame C. B is the under revolving cutter-head for cutting the shoulder and one side of a tenon, and hung in adjustable horizontal frame D. ct is A a horizontal shaft or arbor upon which the cutter-head A is attached, and is revolved by the pulley a'. b is a horizontal shaft or arbor 4 upon which the cutter-head Bis attached, and

is revolved by the pulley b. E is a revolving cutter, for coping the sash, on upright shaft e.

is a revolving, wabbling or drunken sawcutter, fast on upright shaft f, revolved by pulley f adjustable horizontally on bar f by the screw f3, and vertically on the upright support Wl by screw f4. G is a revolving, wabbling or drunken saw-cutter fast on upright shaft g, and adjustable in a similar manner to cutter F. These two cutters cut the incline sides of the dovetail in the joint of the sash and are made to be adjusted to the inoline, and cut at one passing through the machine the doveta-il. His a horizontally sliding table provided with a tipping bearing for the proper incline or angle of the dovetail. I and J are formers that tip the table H to any required inclination. K is a pivoted lever to adjust the former I, and L is a pivoted lever to adjust the former J. M is a horizontal bar with sliding heads, m, sliding thereon, with gage-points therein for marking or gaging the stuff where mortises are to be made. N

.oscillate plate O and wheels R and E.

is also a horizontal bar on the fence of the sliding table, with heads, n, to mark the other side of the stuff being operated upon. W is the base or supporting frame of the machine, and has an upright part, W', to support the movable or adjustable frames O and D, and the means for adjusting them, which consists of a train of gear-wheels, R, R,U, and V, of which wheel U is upon a screw-shaft, S, that is attached to the adjustable frame C, and by revolving it in one direction the frame C will be raised, or by reversing the revolution it will be lowered; while wheel V is attached to screw shaft T that is connected with the frame D, and operates frame D in the same manner as the screw-shaft S operates frame C. 0 is an oscillating triangular plate pivoted centrally on the top of frame W', with gear-wheels It and R pivoted to two angles 0r corners, while hand-lever P is pivoted to the other angle or corner. Lever P has indents 1,2, and 3 on its side, which indents are to receive the stud p as the leverl is made to Stud p is fast on the top of frame W. s isa spring, one end secured to the top plate of frame W', and the other or free end bearing againstlever P to keep it upon stud lo,l so that the plate O with the gear-wheels It and R will beheld in the proper position. By this arrangement of gear attached to screw-shafts S and T both shafts canbe made to operate frames G and D in the same or opposite directions.; or one shaft only may be turned and move the frame to which it is attached in either direction-as, for example, when indent l is on stud p the two screw-shafts move in opposite directions and will force the frames C and D in opposite directions, and when indent 2 is on the stud the triangular plate O has brought the intermediate wheels R and R on a line with shaft S and each other, disconnecting screwshaft from shaft S, when either shaft can be moved independently of the other; and when indent 3 is on the stud p the shafts S and T are connected by a single intermediate wheel, R, when by revolving one shaft by the crankhandle S the other shaft Will move in the same direction, and consequently both of the adjustable frames G and D will be moved in the "same direction, according to the direction that the shafts S and T may be revolved in. In sash stiles cutter A cuts the thickness or relishes, saw F cuts the straight and G the incline or dovetail side, and as saw G can be inclined to any desired inclination Will cut any desired angle in dovetails that may be required.

By this construction and arrangement of devices by once .passing the prepared and dressed stuff through the machine the dovetail joints in sash are fully completed.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

1. In a Window-sash machine the adjustable cutters A and B, in combination with the ad- ,Y

justable Wabbling` or drunken cutters F and G and sliding tipping table E, in the manner and for the purpose substantially as shown and described.

2. The hand-lever P With indents 1,2, and 3 thereon and stud p, intermediate gear-Wheels R and R', triangular plate O, gear-Wheels U and V, and screw-shafts S and T, with the movable frame O and D, substantially in the manner and for the purpose described.

3. The adjustable markers m and u, in combination with the sliding tipping table H and cutters A B F and G, substantially in the manner and for the purpose described.
